Automation timer before trigger question

Hello,

I have this automation that works fine.
Is there a way to monitor the timer when it is on? In the automation it logs only if the timer triggers the action after 30 minutes, but if the timer is cancelled (temp goes below/equal 24) nothing seems to get logged.

  - platform: device
    device_id: xxxxx
    domain: climate
    entity_id: yyyyy
    type: current_temperature_changed
    above: 24
    below: 40
    for:
      hours: 0
      minutes: 30
      seconds: 0
condition:

No - the automation doesn’t start until the trigger fires - but the history of the entity should show changes.

Thanks, i reformated the code…
